Half you guys have compressors which means you can buy a decent use spray gun on the cheap. PPGs econo brand is dirt cheap yet still a proper urethane base/clear. I bought a gallon of classic red and a gallon of urethane clear for 300 bucks. Any color other then red should be quite a bit less. How much are these Rusto jobs costing? |
Whats the exact paint you used from the rustoleum line? I've had nothing but bad luck. The few rustoleum paints i've used have been extremely thin and impossible to wet sand even with 3-4 coats.

All of the old timers on the forums that paint tractors, old lanterns, etc swear by the Rustoleum Professional. They say it dries quicker, runs less, and has a better shine. It will say professional not Stops Rust. Every thread I read they were complaining of runs, I noticed two correlations they were either painting with stops rust or diluding 50/50. I'm cutting in with the small brush with 100% paint and then rolling with 8 parts paint 1 part mineral spirits and 1 part hardener. I'm not measuring just a little splish splash. This is the exact paint I'm using.

Its has good shine and depth, I wonder how long I need to wait to wet sand it. A month? I like that the color varies a lot in different light. https://www.miataturbo.net/attachmen...ine=1392444416 https://www.miataturbo.net/attachmen...ine=1392444416 http://i16.photobucket.com/albums/b1...ps50bc7669.jpg |
I've had decent luck using the Rustoleum Professional in a HF HVLP (not the cheapest, go one grade up) and thinning the paint using Acetone instead of thinner at a 65/35 or 70/30 ratio. Mess with the settings on the gun, a little practice and I was pretty surprised at the results.

I painted a boat with that same stuff. It never hardened like real auto paint. It has that strange feel, I dunno, like a fire hydrant. Just kind of soft, even after a year in the sun.

I think the reason you thin the rustoleum is to make a thin, easier/faster drying coat. You sand between coats to flatten the surface prior to the next coat. When you sand you'll know if its thoroughly dry or not. Layering multiple thin coats helps with the drying process, which in turn helps you to not end up with a thick eternally mushy paint job.
That being said, I would not use rustoleum. The process that spread web-wide years ago isn't because rustoleum is great paint, its because the process can yield good results from cheap products applied with a brush. If you did the same thing with a better quality paint, the results would be far superior. You absolutely CAN paint a car with Dupont, PPG, whatever paint in the same manner and have a much better, longer lasting paint job. Just don't use pearl or metallic colors as the sanding will "uncover" the "glitter" and ruin the appearance. Real automotive paints, even the lower level brands, have far superior UV protection than rustoleum does. |
